Webb Takes a Fresh Look at a Classic Deep Field
The James Webb Space Telescope has captured an unprecedentedly deep image of the Hubble Ultra Deep Field using its Mid-Infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam), revealing over 2,500 galaxies including hundreds of extremely red, dust-obscured or mature galaxies formed early in cosmic history. This nearly 100-hour observation provides detailed insights into galaxy formation and evolution by resolving structures and light distribution in distant galaxies across billions of years.
